Alan, you are making some huge stencils. I can't imagine making them that thick.
Ok I measured a few screens. I am getting between 6 and 9 percent EOM. I can't imagine having a 20% EOM for spot color jobs. I guess now that I can measure them I need to try a thicker one and see what it does.
I think you'll be pleasantly surprised by your results. I don't know if you ever have to double stroke anything, but we don't like to do that and a big reason we don't have to is stencil thickness. There are 2 things we try and avoid like the plaque around here, double stroking and pfp'ing underbases. Anything I can do to not have to do those things is what we do. It's another reason why we are still using a good number of lower mesh counts, where the recent trend is 80's, 110's and 137's are almost non-existent in many shops, I'll use the hell out of them. And the more I use the Murakami S thread, the more I love it. I can see our shop using only the newman roller mesh and murakami S threads.
